my function to return the first 4 item in an iterable will not work.

What am I missing? should I just give up on this coding thing at this point since I have to get help on these stupid things that seem so freaking simple?

slices.py 
def first_4(iterable):
    return iterable[0,3]

I believe when you do slices you put the second argument one number past what you want the last number to be, so try [0, 4]. It should add everything up to but not including the 4 index.

The return should look like this:

return iterable[0:4]

You forgot colon & need the number 4

Yep it's all about remembering all of the syntax- I even forgot that it requires a colon vs. a comma. I've been working on java more so than Python lately ;)
